Unity in the opinions of the Supreme Leader 6

The unity of Muslims is a definite Qur'anic promise; this is not an arbitrary or optional thing; we must look at this as a duty. The Qur'an has commanded: “hold fast, all together, to Allah's cord, and do not be divided [into sects). That is even in holding to Allah's cord, we should get together, this is an order, this is a ruling that must be obeyed.
